一般注記The numerical accuracy is investigated for two second-order accurate finite difference schemes: a predictor-corrector form of the Crank-Nicolson scheme and the DuFort-Frankel scheme, applied to the Cebeci-transformed two-dimensional incompressible boundary layer equations. The relation between the absolute error of the velocity gradient at the wall and the step width of the finite difference calculation was obtained for the Howarth problem. The result shows that the second-order accuracy is numerically realized when a coupled algorithm for the equations of continuity and momentum is used in a predictor-corrector form of the Crank-Nicolson scheme. The DuFort-Frankel scheme, which is explicit, also maintains the second-order accuracy when a sufficiently small streamwise step width is taken. Comparisons of results for the numerical accuracy and the computation speed with those of the well-known Keller’s Box scheme are also discussed.
